The process of liquid-phase sintering of aluminum-copper powder compacts comprises two main stages — growth and shrinkage. Growth is due to diffusion of copper atoms from the liquid phase into the solid, with the formation of liquid interlayers at the grain and subgrain boundaries. Compacts from powder mixtures containing large aluminum particles exhibit increased growth in the first stage of sintering, which may be due to nonuniform reaction of the liquid phase on the peripheries of the particles, resulting in the appearance of local strains and further separation of the solid-phase particles. |
